I think dreamsigns for those who can't pick out specifics should be made more abstract. For example most of my dreams occur in a place that I don't recognize IRL. This may not be a specific sign, such as all my dreams having the same red car, but it's enough for me to reality check every time I enter a new area to confirm that I know where I am.

I'm sure by going over those five dreams you can make a list of 5 instances to RC over each day. In any event a big congratulations to you.
